As before, tickets for this conference will still be distributed by lottery. From today until Friday, April 10 (Beijing time April 18, 10), developers can purchase tickets through the WWDC website, and the specific lottery results will be announced at 5: 00 on Monday, April 20th, Pacific Daylight Time.
Of course, it should be noted that even if Apple released iOS 9 at this conference, the official launch will have to wait until September or even 10, that is, when the new generation of iPhone goes on the market.
